Walt Disney Studios is looking for extras to appear in what it calls “a major motion picture based on a hit television series starring a well known pop teen sensation.”Hmm. … Could that be Disney’s upcoming “Hannah Montana” movie that’s set to be filmed in Middle Tennessee and Los Angeles?A receptionist for Dave Wong, the studio’s vice president of publicity, said Friday that they’re not ready to confirm that. But strangely enough, the on-hold music at Wong’s office was “Ready, Set, Don’t Go,” a country duet by “Hannah Montana” star Miley Cyrus’ and her father, Billy Ray Cyrus.The open casting call for extras is 11 a.m. to 2 p.m. on Sunday, April 6, at the Sommet Center in Nashville.The studio says it’s looking for background actors of all ages for non-speaking parts. No experience is necessary.Everyone must bring a recent nonreturnable snapshot and a pen. Filming begins in and around Nashville on May 6.
